QString Class

Construct the QueryString from a query string.

Construct the QueryString from the HttpContext's HttpRequest. Note that this constructor handles the case where the HttpContext is null, resulting in an empty collection.

Construct the QueryString from an HttpRequest.

Gets or Sets this collection's child object ID

The number of elements actually contained in the ArrayList.

When set, sets or clears the IsDirty bit on each Property in the collection. When retrieved, returns true if the IsDirty bit is set on any Property in the collection

true if the ArrayList has a fixed size; otherwise, false. The default is false.

Returns true if the collection is read-only. (Default is false)

true if access to the internal ArrayList is synchronized (thread-safe); otherwise, false. The default is false.

Indexer declaration

Indexer declaration

True if the collection has been loaded, False otherwise. Note that the collection may have been loaded and still remain empty. Also, the Load methods do not honor this flag. You can test LoadedDate to determine the UTC date/time that this collection was last marked as Loaded.

Gets the UTC date/time that this collection was last marked as Loaded. If the collection has not been so marked, DateTime.MinValue is returned.

Adds an item to the collection

Add a property object to the collection

Adds a property to the collection

Add a new property object to the collection

Adds an item to the collection at the specified index. To append an item use -1 or the collection item count as the index.

Clears the collection

Clears the specified attribute (or multiple attribute bits if the attr value includes multiple attribute bits) in the specified property. The property is assumed to be an int (presumably representing an enumeration) defaulting to zero if not found. If the property already exists then the provided attr bits are cleared from the existing value (using a bit-wise AND of the complement). If the property does not already exist then it is NOT added. You can use IsAttrSet(String, Enum) to determine if one or more attribute bits are set. Use SetAttr(String, Enum) to set a bit or bits.

Returns a value as an double for a property in the collection. If the property doesn't exist, 0 is returned.

Returns a value as an double for a property in the collection. If the property doesn't exist, then the defaultValue is returned.

Returns an enumerator that can iterate through the ArrayList.

Serves as a hash function for a particular type.

Returns a value as an integer for a property in the collection. If the property doesn't exist, then 0 is returned.

Returns a value as an integer (presumably to be interpreted as an enumeration value) for a property in the collection. If the property doesn't exist, then the defaultValue is returned.

Returns a value as an integer for a property in the collection. If the property doesn't exist, then the defaultValue is returned.

Returns an item that matches the specified string index

Returns an item that matches the specified string index

Returns the name of the object (must be an object of type Property)

Returns a value for a property in the collection. If the property doesn't exist or is blank, then an empty string is returned.

Returns a value for a property in the collection. If the property doesn't exist or is blank, then the defaultValue is returned.

Gets the Type of the current instance.

Returns a value for a property in the collection. If the property doesn't exist, then the defaultValue is returned.

Imports a NameValueCollection into this collection

Imports a tag-string into this collection. The string should be in the format of: name=value;name=value

Imports a collection of properties into this collection

Imports a tag-string into this collection. The string should be in the format of: name=value;name=value

Imports a tag-string into this collection. The string should be in the format of: name=value;name=value

Returns the zero-based index of the first occurrence of an object in the internal ArrayList or in a portion of it.

Returns the index of the item in the collection (by key)

Inserts an element into the internal ArrayList at the specified index

Determines if the specified attribute is set (or any of the specified attributes are set if the attr value includes multiple attribute bits) in the specified property. The property is assumed to be an int (presumably representing an enumeration) defaulting to zero if not found. You can use SetAttr(String, Enum) to set one or more attribute bits. Use ClearAttr(String, Enum) to clear a bit or bits.

Determine if the provided item is marked for deletion.

Returns true if the object is the correct type (Property)

Load overload. This overload loads only from the xmt_properties table.

Loads the properties for all objects of specified type, then assigns them to each object Note that the child objects must implement INQBase

Loads the properties for all objects of specified type, then assigns them to each object Note that the child objects must implement INQBase

Loads the collection of property metadata. This collection is used during load and distribute to distribute a set of properties across a collection and it's collected objects. (e.g. Mapper and Fields).

Loads the collection of property metadata. This collection is used during load and distribute to distribute a set of properties across a collection and it's collected objects. (e.g. Mapper and Fields).

Loads the collection of property metadata. This collection is used during load and distribute to distribute a set of properties across a collection and it's collected objects. (e.g. Mapper and Fields).

Creates a shallow copy of the current Object.

Merge the properties from another Properties collection into this collection.

Construct the parameter portion of a query string. The string will include "&" separators, but no leading "?".

Persist each property marked as PropAttrEnum.persist to the xmt_properties table

Prepares this object for cache

Recalculates the internal hash

Removes the first occurrence of a specific object from the collection

Remove the specified item from the collection.

Removes the element at the specified index

Removes the properties marked with the ToRemove attribute.

Removes the properties marked for deletion.

Resolve the provided expression for query parameter references of the form [<flags>req.<param>] where flags is optional and is one or FieldExpressionAttrs and param is the name of the parameter (and req is literally "req"). References for which no corresponding parameter are found are not resolved. Note that at this time only request parameters are resolved and the ParseEmbeddedFuncs is ignored. If embedded functions need to be parsed you must also call ResolveEmbeddedFunctions(String, IDatabase, ResolveOptions).

Set the specified attribute (or multiple attribute bits if the attr value includes multiple attribute bits) in the specified property. The property is assumed to be an int (presumably representing an enumeration) defaulting to zero if not found. If the property already exists then the provided attr bits are ORed into the existing value. If the property does not already exist then it is created and the value set to the provided attr bits. You can use IsAttrSet(String, Enum) to determine if one or more attribute bits are set. Use ClearAttr(String, Enum) to clear a bit or bits.

Sets an item's value at the specified index.

Sets an item's value at the string index indicated by the parameters.

Sort the list by its key value.

Sort the collection using the provided comparer.

Sort the properties by their values.

Generate a syntactically valid query string.

Generate a syntactially valid query string including only the specified parameters.

Truncate the array starting at the specified index.

Called when the collection is cleared allowing a derived class to clean up.

Determines if the object value is equal to another object. If the two objects are null, then this returns true. There is special handling for guid comparisons (since a guid could be a string formatted in up to 3 different ways). If the special guid handling is not performed, then the object.Equals method is used.
