ArgumentDescriptor
final public class ArgumentDescriptor extends DescriptorBase implements XmlCapable,Serializable(Code)
	An ArgumentDescriptor contains information that defines a single argument that is passed to a procedure/function. Note: Be careful when use ArgumentDescriptor variables or caching ArgumentDescriptor instances, because instances could become invalid during runtime (see MetadataManager ). author: Ron Gallagher version: $Id: ArgumentDescriptor.java,v 1.8.2.1 2005/12/21 22:26:10 tomdz Exp $

Constructor Summary
public	ArgumentDescriptor(ProcedureDescriptor procedureDescriptor) Constructor declaration.

Method Summary
final public FieldDescriptor	getFieldRef() Retrieve the field descriptor that this argument is related to.
public boolean	getIsReturnedByProcedure()
final public int	getJdbcType() Retrieve the jdbc type for the field descriptor that is related to this argument.
final public ProcedureDescriptor	getProcedureDescriptor() Retrieve the procedure descriptor that this object is related to.
public Object	getValue(Object objekt)
public void	saveValue(Object objekt, Object value)
public void	setValue() Sets up this object to represent a null value.
public void	setValue(String fieldRefName, boolean returnedByProcedure) Sets up this object to represent a value that is derived from a field in the corresponding class-descriptor. If the value of `fieldRefName` is blank or refers to an invalid field reference, then the value of the corresponding argument will be set to null.
public void	setValue(String constantValue) Sets up this object to represent an argument that will be set to a constant value.
public String	toString()
public String	toXML()

Constructor Detail

ArgumentDescriptor
public ArgumentDescriptor(ProcedureDescriptor procedureDescriptor)(Code)
	Constructor declaration. By default, this object will be configured so that the value returned by ArgumentDescriptor.fieldSource will be null. To change this, call either version of the setValue method. See Also: ArgumentDescriptor.setValue() See Also: ArgumentDescriptor.setValue(String) See Also: ArgumentDescriptor.setValue(String,boolean)

Method Detail

getFieldRef
final public FieldDescriptor getFieldRef()(Code)
	Retrieve the field descriptor that this argument is related to. This reference can only be set via the ArgumentDescriptor.setValue(String,boolean) method. The current value

getIsReturnedByProcedure
public boolean getIsReturnedByProcedure()(Code)

getJdbcType
final public int getJdbcType()(Code)
	Retrieve the jdbc type for the field descriptor that is related to this argument.

getProcedureDescriptor
final public ProcedureDescriptor getProcedureDescriptor()(Code)
	Retrieve the procedure descriptor that this object is related to. The current value

getValue
public Object getValue(Object objekt)(Code)

saveValue
public void saveValue(Object objekt, Object value)(Code)

setValue
public void setValue()(Code)
	Sets up this object to represent a null value.

setValue
public void setValue(String fieldRefName, boolean returnedByProcedure)(Code)
	Sets up this object to represent a value that is derived from a field in the corresponding class-descriptor. If the value of `fieldRefName` is blank or refers to an invalid field reference, then the value of the corresponding argument will be set to null. In this case, ArgumentDescriptor.getIsReturnedByProcedure will be set to `false`, regardless of the value of the `returnedByProcedure` argument. Parameters: fieldRefName - the name of the field reference that provides thevalue of this argument. Parameters: returnedByProcedure - indicates that the value of the argumentis returned by the procedure that is invoked.

setValue
public void setValue(String constantValue)(Code)
	Sets up this object to represent an argument that will be set to a constant value. Parameters: constantValue - the constant value.

toString
public String toString()(Code)
	Provide a string representation of this object a string representation of this object

toXML
public String toXML()(Code)
