| Field Summary | |
| final protected static int | NULL_INT
A special integer to denote no attribute is assigned. | | final protected static short | NULL_SHORT
A special short to denote no attribute is assigned. |
| Method Summary | |
| final protected static void | append(StringBuffer sb, String attrName, String attrValue)
Appends an attribute to the string buffer,
if attrValue is not null. | | protected static void | append(StringBuffer sb, String attrName, boolean avail)
Appends an attribute to the string buffer,
if avail is true. | | final protected static void | append(StringBuffer sb, String attrName, int val)
Appends an attribute to the string buffer,
if val is not NULL_INT. | | public boolean | getIf()
Returns the if condition. | | public boolean | getUnless()
Returns the unless condition. | | public boolean | isEffective()
Returns whether this tag is effecive. | | final protected static void | put(Map params, String attrName, String attrValue)
Puts an attribute to the map,
if attrValue is not null. | | final protected static void | put(Map params, String attrName, boolean avail)
Puts an attribute to the map. | | final protected static void | put(Map params, String attrName, int val)
Puts an attribute to the map,
if val is not NULL_INT. | | final protected static void | put(Map params, String attrName, Object attrValue)
Puts an object if it is not null. | | public void | setIf(boolean ifcond)
Sets the if condition. | | public void | setUnless(boolean unless)
Sets the unless condition. | | final protected static int | toScope(String scope)
Returns one of
ActionContext.PAGE_SCOPE ,
ActionContext.REQUEST_SCOPE ,
ActionContext.SESSION_SCOPE and
ActionContext.APPLICATION_SCOPE of the specified scope name. |
| NULL_INT | | final protected static int NULL_INT(Code) | | A special integer to denote no attribute is assigned.
|
| NULL_SHORT | | final protected static short NULL_SHORT(Code) | | A special short to denote no attribute is assigned.
|
| append | | final protected static void append(StringBuffer sb, String attrName, String attrValue)(Code) | | Appends an attribute to the string buffer,
if attrValue is not null.
|
| append | | protected static void append(StringBuffer sb, String attrName, boolean avail)(Code) | | Appends an attribute to the string buffer,
if avail is true.
|
| append | | final protected static void append(StringBuffer sb, String attrName, int val)(Code) | | Appends an attribute to the string buffer,
if val is not NULL_INT.
|
| getIf | | public boolean getIf()(Code) | | Returns the if condition.
If the if condition is false, this tag is ignored.
If the unless condition (
AbstractAction.getUnless ) is true, this tag is
ignored, too.
Tags deriving from this class shall invoke
AbstractAction.isEffective to
know the result.
Default: true.
|
| getUnless | | public boolean getUnless()(Code) | | Returns the unless condition.
If the unless condition is true, this tag is ignored.
If the if condition (
AbstractAction.getIf ) is true, this tag is ignored, too.
Tags deriving from this class shall invoke
AbstractAction.isEffective to
know the result.
Default: false.
|
| isEffective | | public boolean isEffective()(Code) | | Returns whether this tag is effecive. If false, this tag does nothing
(as if not specified at all).
|
| put | | final protected static void put(Map params, String attrName, String attrValue)(Code) | | Puts an attribute to the map,
if attrValue is not null.
|
| put | | final protected static void put(Map params, String attrName, boolean avail)(Code) | | Puts an attribute to the map.
Unlike othere put(...), it always puts the specified attribute.
|
| put | | final protected static void put(Map params, String attrName, int val)(Code) | | Puts an attribute to the map,
if val is not NULL_INT.
|
| put | | final protected static void put(Map params, String attrName, Object attrValue)(Code) | | Puts an object if it is not null.
|
| setIf | | public void setIf(boolean ifcond)(Code) | | Sets the if condition.
|
| setUnless | | public void setUnless(boolean unless)(Code) | | Sets the unless condition.
