                                  java.lang.String inputEncoding)
Method Detail

log

public void log(java.lang.String message,
                java.lang.Throwable throwable)
Specified by:
log in interface SSIExternalResolver

addVariableNames

public void addVariableNames(java.util.Collection variableNames)
Description copied from interface: SSIExternalResolver
Adds any external variables to the variableNames collection.

Specified by:
addVariableNames in interface SSIExternalResolver
Parameters:
variableNames - the collection to add to

getReqAttributeIgnoreCase

protected java.lang.Object getReqAttributeIgnoreCase(java.lang.String targetName)

isNameReserved

protected boolean isNameReserved(java.lang.String name)

setVariableValue

public void setVariableValue(java.lang.String name,
                             java.lang.String value)
Description copied from interface: SSIExternalResolver
Set the named variable to the specified value. If value is null, then the variable will be removed ( ie. a call to getVariableValue will return null )

Specified by:
setVariableValue in interface SSIExternalResolver
Parameters:
name - of the variable
value - of the variable

getVariableValue

public java.lang.String getVariableValue(java.lang.String name)
Specified by:
getVariableValue in interface SSIExternalResolver

getCGIVariable

getCurrentDate

public java.util.Date getCurrentDate()
Description copied from interface: SSIExternalResolver
Returns the current date. This is useful for putting the SSI stuff in a regression test. Since you can make the current date a constant, it makes testing easier since the output won't change.

Specified by:
getCurrentDate in interface SSIExternalResolver
Returns:
the data
