Field Detail

• bodyText

  protected java.lang.String bodyText

  The body text collected from this element.

• targetOffset

  protected final int targetOffset

  location of the target object for the call, relative to the top of the digester object stack. The default value of zero means the target object is the one on top of the stack.

• methodName

  protected final java.lang.String methodName

  The method name to call on the parent object.

• paramCount

  protected final int paramCount

  The number of parameters to collect from MethodParam rules. If this value is zero, a single parameter will be collected from the body of this element.

• paramTypes

  protected java.lang.Class<?>[] paramTypes

  The parameter types of the parameters to be collected.

• paramClassNames

  protected final java.lang.String[] paramClassNames

  The names of the classes of the parameters to be collected. This attribute allows creation of the classes to be postponed until the digester is set.

• useExactMatch

  protected boolean useExactMatch

  Should MethodUtils.invokeExactMethod be used for reflection.

Constructor Detail

• CallMethodRule

  public CallMethodRule(java.lang.String methodName,
                int paramCount)

  Construct a "call method" rule with the specified method name. The parameter types (if any) default to java.lang.String.

  Parameters:

  methodName - Method name of the parent method to call

  paramCount - The number of parameters to collect, or zero for a single argument from the body of this element.

• CallMethodRule

  public CallMethodRule(int targetOffset,
                java.lang.String methodName,
                int paramCount)

  Construct a "call method" rule with the specified method name. The parameter types (if any) default to java.lang.String.

  Parameters:

  targetOffset - location of the target object. Positive numbers are relative to the top of the digester object stack. Negative numbers are relative to the bottom of the stack. Zero implies the top object on the stack.

  methodName - Method name of the parent method to call

  paramCount - The number of parameters to collect, or zero for a single argument from the body of this element.

• CallMethodRule

  public CallMethodRule(java.lang.String methodName)

  Construct a "call method" rule with the specified method name. The method should accept no parameters.

  Parameters:

  methodName - Method name of the parent method to call

• CallMethodRule

  public CallMethodRule(int targetOffset,
                java.lang.String methodName,
                int paramCount,
                java.lang.Class<?>[] paramTypes)

  Construct a "call method" rule with the specified method name and parameter types. If paramCount is set to zero the rule will use the body of this element as the single argument of the method, unless paramTypes is null or empty, in this case the rule will call the specified method with no arguments.

  Parameters:

  targetOffset - location of the target object. Positive numbers are relative to the top of the digester object stack. Negative numbers are relative to the bottom of the stack. Zero implies the top object on the stack.

  methodName - Method name of the parent method to call

  paramCount - The number of parameters to collect, or zero for a single argument from the body of this element

  paramTypes - The Java classes that represent the parameter types of the method arguments (if you wish to use a primitive type, specify the corresponding Java wrapper class instead, such as java.lang.Boolean.TYPE for a boolean parameter)
