Class SlotKeyMap

java.lang.Object

io.mindspice.simplypages.core.SlotKeyMap

public class SlotKeyMap
extends Object

Mutable string-keyed slot value map used mainly as a legacy bridge API.

This map stores values as TypedValue to preserve runtime type metadata. For modern rendering, prefer RenderContext and SlotKey directly.

Mutability/thread-safety: mutable and not thread-safe. Treat as request-scoped data. For reuse, stop mutating shared instances and render stable structures with per-request context data.

Method Summary

Modifier and Type	Method	Description
static SlotKeyMap	create()	Factory for an empty slot map.
static SlotKeyMap	fromMap(Map<String,?> plainMap)	Converts a plain object map into a typed slot map.
static SlotKeyMap	fromRenderContext(RenderContext context)	Legacy bridge: convert explicit entries from a render context into a string-key map.
Optional<TypedValue>	get(String slotName)	Returns the typed value wrapper for slotName, when present.
<T> T	getOrDefault(String slotName, T defaultValue)	Returns the stored value, or defaultValue when absent.
<T> Optional<T>	getValue(String slotName, Class<T> expectedType)	Returns the value for slotName cast as expectedType.
Map<String, TypedValue>	getValues()	Returns an unmodifiable snapshot of internal typed values.
boolean	isEmpty()	Returns whether the map has no entries.
SlotKeyMap	put(String slotName, Class<?> type, Object value)	Stores value with an explicit runtime type token.
SlotKeyMap	putBoolean(String slotName, Boolean value)	Stores a boolean value for slotName.
SlotKeyMap	putInt(String slotName, Integer value)	Stores an integer value for slotName.
SlotKeyMap	putString(String slotName, String value)	Stores a string value for slotName.
int	size()	Returns the number of stored entries.
Map<String,Object>	toPlainMap()	Returns a mutable plain object copy of this map's values.
RenderContext	toRenderContext(Map<String, SlotKey<?>> slotMapping)	Legacy bridge: convert this string-key map to a render context using the provided slot key mapping.
SlotKeyMap	withDefaults(SlotKeyMap defaults)	Returns a merged copy where this map overrides defaults for duplicate keys.

Method Details

create

public static SlotKeyMap create()

Factory for an empty slot map.

putString

public SlotKeyMap putString(String slotName,
 String value)

Stores a string value for slotName.

putBoolean

public SlotKeyMap putBoolean(String slotName,
 Boolean value)

Stores a boolean value for slotName.

putInt

public SlotKeyMap putInt(String slotName,
 Integer value)

Stores an integer value for slotName.

put

public SlotKeyMap put(String slotName,
 Class<?> type,
 Object value)

Stores value with an explicit runtime type token.

Parameters:

slotName - slot name

type - expected runtime type of value

value - value to store; may be null

Returns:

this map

get

public Optional<TypedValue> get(String slotName)

Returns the typed value wrapper for slotName, when present.

getValue

public <T> Optional<T> getValue(String slotName,
 Class<T> expectedType)

Returns the value for slotName cast as expectedType.

getOrDefault

public <T> T getOrDefault(String slotName,
 T defaultValue)

Returns the stored value, or defaultValue when absent.

withDefaults

public SlotKeyMap withDefaults(SlotKeyMap defaults)

Returns a merged copy where this map overrides defaults for duplicate keys.

fromMap

public static SlotKeyMap fromMap(Map<String,?> plainMap)

Converts a plain object map into a typed slot map.

Entries with null values are skipped.

fromRenderContext

public static SlotKeyMap fromRenderContext(RenderContext context)

Legacy bridge: convert explicit entries from a render context into a string-key map. Slot names are derived from SlotKey.name().

toRenderContext

public RenderContext toRenderContext(Map<String, SlotKey<?>> slotMapping)

Legacy bridge: convert this string-key map to a render context using the provided slot key mapping. Entries with no matching key are ignored.

toPlainMap

public Map<String,Object> toPlainMap()

Returns a mutable plain object copy of this map's values.

getValues

public Map<String, TypedValue> getValues()

Returns an unmodifiable snapshot of internal typed values.

isEmpty

public boolean isEmpty()

Returns whether the map has no entries.

size

public int size()

Returns the number of stored entries.
