Methods
addNodes()
addNodes(
nodes):void
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:43
Add new leaf nodes from a compaction.
Parameters
nodes
Returns
void
clear()
clear():
void
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:229
Reset the chain.
Returns
void
collapse()
collapse():
Promise<SummaryChainNode[]>
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:54
Collapse the chain if it exceeds the token budget. Merges the oldest leaf nodes into a higher-level summary. Returns any newly created parent nodes.
Returns
Promise<SummaryChainNode[]>
formatForPrompt()
formatForPrompt():
string
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:88
Format the chain for inclusion in a prompt.
Returns
string
getActiveChain()
getActiveChain():
SummaryChainNode[]
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:83
Get the active chain — top-level nodes without parents, sorted by turn range.
Returns
getAllNodes()
getAllNodes():
SummaryChainNode[]
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:120
Get all nodes (including absorbed children, for audit/UI).
Returns
getCoveredRange()
getCoveredRange(): [
number,number] |null
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:127
Get the full turn range covered by the chain.
Returns
[number, number] | null
getTotalTokens()
getTotalTokens():
number
Defined in: packages/agentos/src/cognition/memory/pipeline/context/RollingSummaryChain.ts:112
Total tokens across all active (non-absorbed) nodes.
Returns
number
