Class CodeTemplateManager

java.lang.Object

org.fife.ui.rsyntaxtextarea.CodeTemplateManager

public class CodeTemplateManager
extends Object

Manages "code templates."

All methods in this class are synchronized for thread safety, but as a best practice, you should probably only modify the templates known to a CodeTemplateManager on the EDT. Modifying a CodeTemplate retrieved from a CodeTemplateManager while not on the EDT could cause problems.

public CodeTemplate[] getTemplates()

Returns the templates currently available.

Returns:

The templates available.

isValidChar

public static final boolean isValidChar(char ch)

Parameters:

ch - The character to check.

Whether the character is a valid template character.

removeTemplate

public boolean removeTemplate(CodeTemplate template)

Returns the code template with the specified id.

replaceTemplates

public void replaceTemplates(CodeTemplate[] newTemplates)

Replaces the current set of available templates with the ones specified.

Parameters:

newTemplates - The new set of templates. Note that we will be taking a shallow copy of these and sorting them.

saveTemplates

public boolean saveTemplates()

Saves all templates as XML files in the current template directory.

Returns:

Whether or not the save was successful.

setInsertTrigger

public void setInsertTrigger(KeyStroke trigger)

Sets the "trigger" character for templates.

Parameters:

trigger - The trigger character to set for templates. This means that when this character is pressed in an RSyntaxTextArea, the last-typed token is found, and is checked against all template ID's to see if a template should be inserted. If a template ID matches, that template is inserted; if not, the trigger character is inserted. If this parameter is null, no change is made to the trigger character.

See Also:

getInsertTrigger(), getInsertTriggerString()

setTemplateDirectory

public int setTemplateDirectory(File dir)

Sets the directory in which to look for templates. Calling this method adds any new templates found in the specified directory to the templates already registered.

Parameters:

dir - The new directory in which to look for templates.

Returns:

The new number of templates in this template manager, or -1 if the specified directory does not exist.
