Method Detail

save

public void save(Branch branch)

Specified by:

save in interface BranchService

getBranchDAO

public BranchDAO getBranchDAO()

setBranchDAO

public void setBranchDAO(BranchDAO branchDAO)

deleteBranchStates

public void deleteBranchStates(List statesToBeDeleted)

Specified by:

deleteBranchStates in interface BranchService

resolveScopedVariable

private BranchState resolveScopedVariable(Branch branch,
                                          String name)

Walks up the Branch/scope hierarchy trying to find a variable with the specified name

Parameters:

branch - the lowermost branch at which to start the search

name - name of the variable to search for

Returns:

a BranchState object in the first Branch/scope in which the variable was found

getScopedVariableValue

public String getScopedVariableValue(Branch branch,
                                     String name)

Description copied from interface: BranchService

Responsible for inspecting the branch hierarchy/scope and returning a value for the variable name if it exists somewere in scope.

Specified by:

getScopedVariableValue in interface BranchService

Parameters:

branch - the lowermost scope to start resolution

Returns:

a value for the key if it exists somewere in scope

setScopedVariableValue

public String setScopedVariableValue(Branch branch,
                                     String name,
                                     String value)

Description copied from interface: BranchService

Responsible for setting a value in the branch hierarchy/scope. If the variable name exists in a scope, it will be updated as opposed to created in a lower scope.

Specified by:

setScopedVariableValue in interface BranchService

Parameters:

branch - the lowermost scope to start resolution

value - the value to set for the variable

Returns:

the replaced value of the variable, if the variable was already defined, or null otherwise
