Record Class ContextCacheConfig

java.lang.Object
java.lang.Record
com.google.adk.agents.ContextCacheConfig
Record Components:
cacheIntervals - maximum number of invocations that reuse the same cache before it is refreshed; must be from 1 to 100
ttl - time-to-live of the cache; must be a whole number of seconds, at least one
minTokens - minimum prompt token count of the agent's previous request needed to create a cache; raise it to skip small requests, where cache storage can cost more than it saves; must not be negative
createHttpOptions - HTTP options, such as a timeout, for the call that creates a cache, or null to use the client's defaults; if that call fails, the request is sent without a cache
public record ContextCacheConfig(int cacheIntervals, Duration ttl, int minTokens, @Nullable com.google.genai.types.HttpOptions createHttpOptions) extends Record
Configures context caching for all agents in an app. Without it, nothing is cached.

      @Deprecated @InlineMe(replacement="this.cacheIntervals()") public int maxInvocations()
      Deprecated.
      Use cacheIntervals(), the name ADK Python and ADK Kotlin use.
      Returns cacheIntervals().

    • getTtlString

      public String getTtlString()
      Returns the TTL in the "<seconds>s" form that the Gemini API uses.

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
