com.google.clearsilver.jsilver.data.LocalAndGlobalData
- All Implemented Interfaces:
- Data
public class LocalAndGlobalData
- extends ChainedData
This is a special implementation of ChainedData to be used for holding the local and global Data
objects (like local and global HDFs in Clearsilver). It prevents writes and modifications to the
global Data object and applies them all to the local data object.
Constructor Summary |
LocalAndGlobalData(Data local,
Data global)
Creates a Data object that encapsulates both request-scoped local HDF and an application
global-scoped HDF that can be read from the template renderer. |
LocalAndGlobalData(Data local,
Data global,
boolean allowGlobalDataModification)
Creates a Data object that encapsulates both request-scoped local HDF and an application
global-scoped HDF that can be read from the template renderer. |
Method Summary |
Data |
createChild(String path)
Retrieves the HDF object that is the root of the subtree at hdfpath, create the subtree if it
doesn't exist |

LocalAndGlobalData
public LocalAndGlobalData(Data local,
Data global)
- Creates a Data object that encapsulates both request-scoped local HDF and an application
global-scoped HDF that can be read from the template renderer. Part of the backwards
compatibility with JNI Clearsilver and its globalHdf support.
- Parameters:
local
- the request-specific HDF data that takes priority.global
- application global HDF data that should be read but not written to from the
template renderer.
LocalAndGlobalData
public LocalAndGlobalData(Data local,
Data global,
boolean allowGlobalDataModification)
- Creates a Data object that encapsulates both request-scoped local HDF and an application
global-scoped HDF that can be read from the template renderer. Part of the backwards
compatibility with JNI Clearsilver and its globalHdf support. We wrap the global HDF in an
UnmodifiableData delegate
- Parameters:
local
- the request-specific HDF data that takes priority.global
- application global HDF data that should be read but not written to from the
template renderer.allowGlobalDataModification
- if true
then enable legacy mode where we do not wrap
the global Data with an Unmodifiable wrapper. Should not be set to true
unless
incompatibilities or performance issues found. Note, that setting to true
could
introduce bugs in templates that acquire local references to the global data structure
and then try to modify them, which is not the intended behavior.
createChild
public Data createChild(String path)
- Description copied from interface:
Data
- Retrieves the HDF object that is the root of the subtree at hdfpath, create the subtree if it
doesn't exist
- Specified by:

in interface Data
- Overrides:
