public class StaticMethodModel

extends NamedMethodCallModel

A rule clause representing an invokation of a static method on an arbitrary java class. This can only be used as a rule action currently. A static-method requires a type-alias, which is the java class which contains the static method which will be executed. The arguments of a static method call can be:

• literals: BigInteger, BigDecimal, Double, Float, Integer, Long, Boolean, Strings
• VariableArgument (not if an action with OR'ed conditions).
• PropertyRefArgument (not if an action with OR'ed conditions).
• UnknownArgument

Method Detail

setXmlObject

public void setXmlObject(String clauseType,
                         org.apache.xmlbeans.XmlObject clause)
                  throws IllegalArgumentException

Description copied from class: ClauseModel

Initialize this clause model with a type and a root object.

This will fire ChangeEvents for clauseType and rootXmlObject.

Subclasses should override to call super.setXmlObject() and do any type checking and verification.

It is not expected that ClauseModels are valid after a call to this method which throws an exception, although the caller could recall this method with valid data.

Overrides:

setXmlObject in class ClauseModel

Parameters

clauseType - the clause type of the clause.

clause - the root xml object of the clause.

Throws

IllegalArgumentException - thrown if the clause is not valid for the ClauseModel or clauseType.

createNewXmlObject

public org.apache.xmlbeans.XmlObject createNewXmlObject(String clauseType)
                                                 throws IllegalArgumentException

Description copied from class: ClauseModel

Create a new, empty root object for the specified clauseType.

Subclasses need to implement this to create an appropriately typed and filled root XmlObject which represents the ClauseModel. The return value from this needs to be accepted from ClauseModel.setXmlObject(java.lang.String, org.apache.xmlbeans.XmlObject) for the specified clauseType.

Specified by:

createNewXmlObject in class ClauseModel

Parameters

clauseType - the clause type of the clause.

Returns

a new, empty initialize root object.

Throws

IllegalArgumentException - thrown on an unsupproted clauseType.

clearCachedData

public void clearCachedData()

Description copied from class: NamedMethodCallModel

Clear any cached data. Subclasses can override if they have additional cached data.

Overrides:

clearCachedData in class NamedMethodCallModel

determineIsComplete

protected boolean determineIsComplete()

Override to include a check to make sure the type-alias is valid.

Overrides:

determineIsComplete in class NamedMethodCallModel

See Also

ClauseModel.isValidTypeAlias(String)

getStaticMethod

protected com.bea.p13n.expression.schema.StaticMethod getStaticMethod()

Get the underlying StaticMethod XmlObject.

getTypeAlias

public String getTypeAlias()

Get the fully-qualified java class name the method belongs to.

setTypeAlias

public void setTypeAlias(String typeAlias)

Set the fully-qualified java class name the method belongs to.

getMethodArgumentListFromXmlObject

protected com.bea.p13n.expression.schema.MethodArgumentList getMethodArgumentListFromXmlObject(boolean create)

Description copied from class: MethodCallModel

Get the MethodArgumentList from the underlying method call XmlObject

Specified by:

getMethodArgumentListFromXmlObject in class MethodCallModel

Parameters

create - true to create if not currently set, false to return null if currently set.

Returns

the MethodArgumentList, or null if not set and create==false.

getMethodNameFromXmlObject

protected String getMethodNameFromXmlObject()

Description copied from class: NamedMethodCallModel

Get the method name from the underlying method call XmlObject.

Specified by:

getMethodNameFromXmlObject in class NamedMethodCallModel

removeMethodArgumentListFromXmlObject

protected void removeMethodArgumentListFromXmlObject()

Description copied from class: MethodCallModel

Remove the MethodArgumentList from the underlying XmlObject.

Specified by:

removeMethodArgumentListFromXmlObject in class MethodCallModel

setMethodNameToXmlObject

protected void setMethodNameToXmlObject(String methodName)

Description copied from class: NamedMethodCallModel

Set the method name to the underlying method call XmlObject.

Specified by:

setMethodNameToXmlObject in class NamedMethodCallModel
