ChangeSet

public ChangeSet()

Constructs an empty change set

Method Detail

set

public ChangeSet set(String path,

Sets the value of the given path.

Parameters:

path - The path that needs its value set.

value - The value to set for the given path.

unset

public ChangeSet unset(String path)

Unsets the specified path. If the path points to a dynamic property or a map key it will be removed, if it points to a fixed property it will be set to null, in that case, the target path must point to a nullable property otherwise an error will occur.

Parameters:

path - Path pointing to the requested property.

increment

public ChangeSet increment(String path,

Parameters:

path - The path pointing to a numeric property that needs its value increased.

delta - The delta to increment by.

increment

Parameters:

path - The path pointing to a numeric property that needs its value increased.

delta - The delta to increment by.

increment
