Method Detail

getSymbolicName

public SymbolicName getSymbolicName()

Get the symbolic name of the component

Specified by:

getSymbolicName in class Actor

Returns:

the symbolic name

setName

public void setName(StructuredQName attributeSetName)

Set the name of the attribute-set

Parameters:

attributeSetName - the name of the attribute-set

setDeclaredStreamable

public void setDeclaredStreamable(boolean value)

Say whether this attribute set is declared to be streamable

Parameters:

value - true if the attribute streamable="yes" is present

isDeclaredStreamable

public boolean isDeclaredStreamable()

Ask whether this attribute set is declared to be streamable

Returns:

true if the attribute streamable="yes" is present

setStackFrameMap

public void setStackFrameMap(SlotManager stackFrameMap)

Set the stack frame map which allocates slots to variables declared in this attribute set

Overrides:

setStackFrameMap in class Actor

Parameters:

stackFrameMap - the stack frame map

getFocusDependencies

public int getFocusDependencies()

Determine whether the attribute set has any dependencies on the focus

Returns:

the dependencies

expand

public void expand(Outputter output,
                   XPathContext context)
            throws XPathException

Evaluate an attribute set

Parameters:

output - the destination for the result

context - the dynamic context

Throws:

XPathException - if any failure occurs

getObjectName

public StructuredQName getObjectName()

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

Returns:

the name

export
