Method Detail

canSetParameter

public boolean canSetParameter(String name,
                               Object value)

Description copied from interface: DOMConfiguration

Check if setting a parameter to a specific value is supported.

Specified by:

canSetParameter in interface DOMConfiguration

Parameters:

name - The name of the parameter to check.

value - An object. if null, the returned value is true.

Returns:

true if the parameter could be successfully set to the specified value, or false if the parameter is not recognized or the requested value is not supported. This does not change the current value of the parameter itself.

setParameter

public void setParameter(String name,
                         Object value)
                  throws DOMException

Description copied from interface: DOMConfiguration

Set the value of a parameter.

Specified by:

setParameter in interface DOMConfiguration

Parameters:

name - The name of the parameter to set.

value - The new value or null if the user wishes to unset the parameter. While the type of the value parameter is defined as DOMUserData, the object type must match the type defined by the definition of the parameter.

Throws:

DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.
NOT_SUPPORTED_ERR: Raised when the parameter name is recognized but the requested value cannot be set.
TYPE_MISMATCH_ERR: Raised if the value type for this parameter name is incompatible with the expected value type.

DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.

getParameterNames

public DOMStringList getParameterNames()

Description copied from interface: DOMConfiguration

The list of the parameters supported by this DOMConfiguration object and for which at least one value can be set by the application. Note that this list can also contain parameter names defined outside this specification.

Specified by:

getParameterNames in interface DOMConfiguration

normalize

public void normalize(Node node)
