The property map of a native object.

A property map is a collection of object properties which require custom implementation of get and/or put operations. Each property in the property map has associated integer selector. Selectors are unique within property maps; they are used by the interpreter to select appropriate get/put procedures for each property in the property map.

Property maps can be attached to native objects (see the CNativeObject class).

Add

void Add(
    const CPropertyName &propertyName,
    int nSelector,
    bool bReadOnly=false);

Adds a property to this property map.

Parameters:

propertyName - the property name

nSelector - the selector

bReadOnly - indicates whether the property has the ReadOnly attribute

Find

int Find(const CPropertyName &propertyName);

Looks up a property in this property map.

Parameters:

propertyName - the property name to look up

Returns:

the index (zero-based) of the specified property in this property map; -1 if the property is not found

GetName

CString GetName(int nIndex);

Returns a string representation of a property name at the specified index in this property map.

Parameters:

nIndex - the index (zero-based)

Returns:

the string representation of a property name at the specified index in this property map

GetSelector

int GetSelector(int nIndex);

Returns a selector at the specified index in this property map.

Parameters:

nIndex - the index (zero-based)

Returns:

the selector at the specified index in this property map

GetAttributes

int GetAttributes(int nIndex);

Returns attributes at the specified index in this property map.

Parameters:

nIndex - the index (zero-based)

Returns:

the attributes at the specified index in this property map

Next

int Next(int nIndex);

Returns the index of the property in this property map which follows the property with the given index.

Parameters:

nIndex - the starting index (zero-based)

Returns:

the index (zero-based) of the property in this property map which follows the property with the given index; -1 if there is no such property (that is, the starting index points to the last property in this property map)
