@Nullable
public final IPSErrorHandler getErrorHandler()

Returns:

The error handler passed in the constructor. May be null.

getVariableResolver

@Nullable
public final XPathVariableResolver getVariableResolver()

Returns:

The variable resolver to be used. May be null.

getFunctionResolver

@Nullable
public final XPathFunctionResolver getFunctionResolver()

Returns:

The function resolver to be used. May be null.

readSchema

@Nonnull
@OverrideOnDemand
public PSSchema readSchema(@Nonnull
                                           com.helger.commons.io.resource.IReadableResource aResource,
                                           @Nullable
                                           IPSErrorHandler aErrorHandler)
                    throws SchematronException

Read the specified schema from the passed resource.

Parameters:

aResource - The resource to read from. Never null.

aErrorHandler - The error handler to use. May be null.

Returns:

The read schema. May not be null.

Throws:

SchematronException - In case there is an error reading.

getQueryBinding

@Nonnull
@OverrideOnDemand
public IPSQueryBinding getQueryBinding(@Nonnull
                                                       PSSchema aSchema)
                                throws SchematronException

Determine the query binding for the read schema.

Parameters:

aSchema - The read schema. Never null.

Returns:

The query binding to use. Never null.

Throws:

SchematronException - In case the determination fails.

createPreprocessor

@Nonnull
@OverrideOnDemand
public PSPreprocessor createPreprocessor(@Nonnull
                                                         IPSQueryBinding aQueryBinding)

Create the pre-processor to be used for createPreprocessedSchema(PSSchema, IPSQueryBinding).

Parameters:

aQueryBinding - The query binding to be determined from the read schema. Never null.

Returns:

The pre-processor to be used.

createPreprocessedSchema

@Nonnull
@OverrideOnDemand
public PSSchema createPreprocessedSchema(@Nonnull
                                                         PSSchema aSchema,
                                                         @Nonnull
                                                         IPSQueryBinding aQueryBinding)
                                  throws SchematronException

Pre-process the read schema, using the determined query binding.

Parameters:

aSchema - The read schema. Never null.

aQueryBinding - The determined query binding. Never null.

Returns:

The pre-processed schema and never null.

Throws:

SchematronException - In case pre-processing fails

createBoundSchema

@Nonnull
public IPSBoundSchema createBoundSchema()
                                 throws SchematronException

The main routine to create a bound schema from the passed resource and phase. The usual routine is to

1. read the schema from the resource - see readSchema(IReadableResource, IPSErrorHandler)
2. resolve the query binding - see getQueryBinding(PSSchema)
3. pre-process the schema - createPreprocessedSchema(PSSchema, IPSQueryBinding)
4. and finally bind it - IPSQueryBinding.bind(PSSchema, String, IPSErrorHandler, javax.xml.xpath.XPathVariableResolver, javax.xml.xpath.XPathFunctionResolver)

Returns:

The bound schema. Never null.

Throws:

SchematronException - In case reading or binding fails.

equals

public boolean equals(Object o)
