MemoryEntry

data class MemoryEntry(val content: Content, val id: String? = null, val author: String? = null, val timestamp: String? = null, val customMetadata: Map<String, Any> = emptyMap())

Represents one memory entry in the Vertex AI Memory Bank.

Serializable because load_memory returns entries to the model through this serializer; the field names below are therefore the ones the model sees.

Constructors

MemoryEntry

constructor(content: Content, id: String? = null, author: String? = null, timestamp: String? = null, customMetadata: Map<String, Any> = emptyMap())

Types

Builder

class Builder

Fluent builder for MemoryEntry, provided primarily for Java callers. Any property left unset falls back to the same default as the constructor.

Properties

author

val author: String?

The author of the memory, or null if not set.

content

val content: Content

The main content of the memory.

customMetadata

@SerialName(value = "custom_metadata")

val customMetadata: Map<String, Any>

Optional key-value metadata associated with this memory. The map must be JSON serializable: load_memory returns it to the model as part of its tool result.

val id: String?

The unique identifier of the memory entry, or null if not yet persisted.

timestamp

val timestamp: String?

The timestamp when the original content of this memory happened, or null if not set. Preferred format is ISO 8601 format.

Functions

toBuilder

fun toBuilder(): MemoryEntry.Builder

Returns a Builder initialized with this instance's properties, primarily for Java callers. Prefer it over copy from Java: copy takes every property positionally, so its signature changes whenever a property is added.
