public void setRecoveryPolicy(int policy)
policy
- the recovery policy to be used. The options are Configuration.RECOVER_SILENTLY
,
Configuration.RECOVER_WITH_WARNINGS
, or Configuration.DO_NOT_RECOVER
.public int getRecoveryPolicy()
public void resetHandlers()
public Mode getUnnamedMode()
public Mode getMode(StructuredQName modeName, boolean createIfAbsent)
modeName
- The name of the mode. Supply null to get the default
mode or Mode.ALL_MODES to get the Mode object containing "mode=all" rulescreateIfAbsent
- if true, then if the mode does not already exist it will be created.
If false, then if the mode does not already exist the method returns null.
public void setTemplateRule(Pattern pattern, Template eh, Mode mode, StylesheetModule module, double priority)
pattern
- Must be a valid Pattern.eh
- The Template to be usedmode
- The processing mode to which this template appliesmodule
- The stylesheet module containing the template rulepriority
- The priority of the rule: if an element matches several patterns, the
one with highest priority is usedPattern

item
- The item to be matchedmode
- The mode for which a rule is requiredmin
- The minimum import precedence that the rule must havemax
- The maximum import precedence that the rule must havec
- The Controller for the transformation

node
- The node to be matchedmode
