Direct Known Subclasses:

BenchXerces2Base, BenchXerces2Deferred

public abstract class BenchXerces2

extends BenchDOM

Abstract base class for benchmarks measuring performance of the Xerces2 DOM document representation. This base class implementation can be customized by subclasses to experiment with options for the representation, in particular for trying the deferred node expansion feature of Xerces. The code used for Xerces2 DOM is identical to that used for Xerces1, but is compiled with a different classpath.

Constructor Detail

BenchXerces2

protected BenchXerces2(java.lang.String config,
                       boolean defer)

Constructor.

Parameters:

config - test configuration name

defer - defer node expansion flag

Method Detail

setDeferExpansion

protected void setDeferExpansion(boolean defer)

Set deferred node expansion mode.

Parameters:

defer - defer node expansion flag

build

protected java.lang.Object build(java.io.InputStream in)

Build document representation by parsing XML. This implementation creates a DOM parser if one does not already exist, then reuses that parser for the duration of a test run..

Overrides:

build in class BenchDocBase

Parameters:

in - XML document input stream

Returns:

document representation

output

protected void output(java.lang.Object doc,
                      java.io.OutputStream out)

Output a document as XML text. This method uses the method defined by the Xerces DOM to output a text representation of the document.

Overrides:

output in class BenchDocBase

Parameters:

doc - document representation to be output

out - XML document output stream

reset

protected void reset()

Reset test class instance. This discards the parser used within a test pass.

Overrides:

reset in class BenchDocBase
