Constructor Details

SubAgentImpl

public SubAgentImpl(org.springframework.ai.tool.ToolCallback delegate,
 CompiledGraph<AgentExecutorEx.State> subGraph)

Creates an instance of a SubAgentImpl record class.

Parameters:

delegate - the value for the delegate record component

subGraph - the value for the subGraph record component

Method Details

name

public String name()

Specified by:

name in interface AgentEx.ToolBehaviour<org.springframework.ai.chat.messages.Message,AgentExecutorEx.State>

addToGraph

public void addToGraph(StateGraph<AgentExecutorEx.State> graph)
                throws GraphStateException

Registers the sub-agent as a node in the parent graph and adapts tool execution requests to the sub-agent message format.

Before invoking the sub-graph, the pending tool call arguments are wrapped as a UserMessage. After completion, the last sub-agent message is converted back into a ToolResponseMessage associated with the original tool call id.

Specified by:

addToGraph in interface AgentEx.ToolBehaviour<org.springframework.ai.chat.messages.Message,AgentExecutorEx.State>

Parameters:

graph - the parent graph receiving this sub-agent node

Throws:

GraphStateException - if graph node registration fails

getToolDefinition

public org.springframework.ai.tool.definition.ToolDefinition getToolDefinition()

Specified by:

getToolDefinition in interface org.springframework.ai.tool.ToolCallback

call

public String call(String toolInput)

Specified by:

call in interface org.springframework.ai.tool.ToolCallback

call

public String call(String toolInput,
 org.springframework.ai.chat.model.ToolContext toolContext)

Specified by:

call in interface org.springframework.ai.tool.ToolCallback

toString

public final 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. All components in this record class are compared with Objects::equals(Object,Object).

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.

delegate

public org.springframework.ai.tool.ToolCallback delegate()

Returns the value of the delegate record component.

Returns:

the value of the delegate record component

subGraph

public CompiledGraph<AgentExecutorEx.State> subGraph()

Returns the value of the subGraph record component.

Returns:

the value of the subGraph record component
