, getAttributeList

Example

The following example retrieves the list of attributes, then iterates over the list, writing each

attribute and its value back to the user:

String[] attribs = request.getAttributeList() ;

int nNumAttribs = attribs.length ;

for( int i = 0; i < nNumAttribs; i++ )

{

String strName = attribs[i] ;

String strValue = request.getAttribute( strName ) ;

response.write( strName + "=" + strValue + "<BR>" ) ;

}

getIntAttribute

Description

Retrieves the value of the passed attribute as an integer. Returns -1 if the attribute does not exist.

Use

attributeExists to test whether an attribute was passed to the tag. Use

getIntAttribute(String,int) to return a default value rather than throwing an exception or

returning -1.

Returns the value of the attribute passed to the tag. If no attribute of that name was passed to the

tag, -1 is returned.
