public void addDeclarationElement(IDeclarationElement pDeclaration)

Description copied from interface: IDeclarationBlock

Add an IDeclarationElement to this block;

Specified by:

addDeclarationElement in interface IDeclarationBlock

Specified by:

clear in interface IDeclarationBlock

copy

public IDeclaration copy()

getDeclarationElement in interface IDeclarationBlock

Returns:

The IDeclarationElement for the given name.

getDeclarationElements

public IDeclarationElement[] getDeclarationElements()

Description copied from interface: IDeclarationBlock

The array of IDeclarationElement instances in this block.

Specified by:

getDeclarationElements in interface IDeclarationBlock

Returns:

The array of IDeclarationElement instances in this block.

isBlock

public boolean isBlock()

Description copied from interface: IDeclaration

true if this declaration has child elements itself.

A IDeclarationElement may be a IDeclarationBlock, supporting nested declarations. You should not use "instanceof IDeclarationBlock" to check this behavior but this method.

isBlock in class Declaration

Returns:

true if this declaration has child elements itself.

moveDown

public void moveDown(IDeclarationElement declaration)

Description copied from interface: IDeclarationBlock

Move element to the position after its current position. This means that the element declaration will be performed later.

If the element is the last declaration or not contained in the block this method does nothing.

Specified by:

moveDown in interface IDeclarationBlock

moveUp

public void moveUp(IDeclarationElement declaration)

Description copied from interface: IDeclarationBlock

Move element to the position before its current position. This means that the element declaration will be performed earlier.

Specified by:

moveUp in interface IDeclarationBlock

removeDeclarationElement

public boolean removeDeclarationElement(IDeclarationElement declaration)

Description copied from interface: IDeclarationBlock

Remove an IDeclarationElement from this block;

Specified by:

removeDeclarationElement in interface IDeclarationBlock

Returns:

true if declaration was removed

size

public int size()

Description copied from interface: IDeclarationBlock

The number of declarations in this block.

Specified by:
