Method Details

forType

public <V> ColumnConfiguration<V> forType(Class<V> type)

Returns the ColumnConfiguration for the given type at the instance level, creating it if it does not yet exist. Modifications to the returned configuration take effect immediately.

Parameters:

type - the column value type

Returns:

the ColumnConfiguration for the given type

resolve

public <V> ColumnConfiguration<V> resolve(Class<V> type)

Returns the effective ColumnConfiguration for the given type, chaining configurations across all levels of the tree. The resolution order, from most to least specific, is:

1. The isolated column-level layer on top of the chain (the node that an EasyColumn's own setters write into).
2. Type-level configuration registered on this instance via forType(Class), walking the class hierarchy from type up to Object.
3. Type-level configuration registered on GlobalEasyGridConfiguration (including the built-in defaults), walking the class hierarchy from type up to Object.

The first non-null value found wins, scope-first: a more specific scope is fully consulted before falling through to the next.

Parameters:

type - the column value type

Returns:

the resolved configuration, never null
