getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Overrides:

getChildCount in class VariableReference

Returns:

an int giving the number of children of this node

getChildAt

public ProgramElement getChildAt(int index)

Returns the child at the specified index in this node's "virtual" child array

Specified by:

getChildAt in interface NonTerminalProgramElement

Overrides:

getChildAt in class VariableReference

Parameters:

index - an index into this node's "virtual" child array

Returns:

the program element at the given position

Throws:

Specified by:

getFirstElementIncludingBlocks in interface SourceElement

Overrides:

getFirstElementIncludingBlocks in class JavaSourceElement

Returns:

the first source element in the syntactical representation of this element, may be equals to this element.
