Methods

apply()

apply(rows, ctx?): Tag[]

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:208

Single-call pipeline: filter → sort → paginate. Most consumers should use this; callers that need the unpaginated total should use applyWithCount instead.

Parameters

rows

readonly Tag[]

ctx?

void

Returns

Tag[]

Inherited from

AbstractQueryExecutor.apply

applyWithCount()

applyWithCount(rows, ctx?): object

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:213

Like apply, but also returns the post-filter / pre-pagination row count. Useful for paged grids that show a total record badge.

Parameters

rows

readonly Tag[]

ctx?

void

Returns

object

items

items: Tag[]

totalCount

totalCount: number

Inherited from

AbstractQueryExecutor.applyWithCount

canExecute()

canExecute(): CanExecuteResult<string, never>

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:148

Inspect the expression tree and report any keys/operators the executor cannot evaluate in-memory. Callers can use this to fall back to an API round-trip instead of subscribing to a selector that will silently return no rows.

Returns

CanExecuteResult<string, never>

Inherited from

AbstractQueryExecutor.canExecute

filter()

filter(rows, ctx?): Tag[]

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:188

Filter rows keeping only those that satisfy the executable expression. Equivalent to rows.filter(r => this.match(r, ctx)) but collocated with sort / paginate / apply for symmetry.

Parameters

rows

readonly Tag[]

ctx?

void

Returns

Tag[]

Inherited from

AbstractQueryExecutor.filter

filterResidual()

filterResidual(rows, residualGroup, ctx?): Tag[]

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:182

Filter rows against the residual AST returned by planBaseSet(). When the group has no leaves left, returns the input unchanged (copied) — the index intersection is already authoritative.

Parameters

rows

readonly Tag[]

residualGroup

ExecutableGroup<string>

ctx?

void

Returns

Tag[]

Inherited from

AbstractQueryExecutor.filterResidual

mapValue()

protected mapValue(entry, expression_key, ctx?): unknown

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:224

Extract the value from the entry based on the expression key.

Parameters

entry

Tag

The model entry to extract the value from.

expression_key

string

the key of the expression to map.

ctx?

void

optional context forwarded to the mapper.

Returns

unknown

Inherited from

AbstractQueryExecutor.mapValue

match()

match(entry, ctx?): boolean

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:141

Evaluate the query against entry. The optional ctx is forwarded to every mapper invocation, enabling cross-model joins.

Parameters

entry

Tag

ctx?

void

Returns

boolean

Inherited from

AbstractQueryExecutor.match

matchGroup()

matchGroup(entry, group, ctx?): boolean

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:176

Same as match, but evaluates the supplied group instead of the top-level expression. Used by selectors to filter the narrowed base set against the residual AST returned by planBaseSet(). Returns true when the residual group has no leaves left to evaluate.

Parameters

entry

Tag

group

ExecutableGroup<string>

ctx?

void

Returns

boolean

Inherited from

AbstractQueryExecutor.matchGroup

paginate()

paginate(rows): Tag[]

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:202

Apply the { skip, take } window from the executable expression. take === null means “no limit” → returns the input slice (copy).

Parameters

rows

readonly Tag[]

Returns

Tag[]

Inherited from

AbstractQueryExecutor.paginate

planBaseSet()

planBaseSet(): BaseSetPlan<string>

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:169

Walk the root expression group and extract every top-level leaf whose mapper carries an index hint and uses an index-eligible operator (Equal for single-valued mappers, Equal / Contains for multi). The remaining (residual) AST is what the executor still needs to evaluate row-by-row after the section narrowed the base set.

Behaviour & guarantees:

Only extracts when the root group’s operator is And. Or roots cannot be safely narrowed without re-introducing rows excluded by other branches.
Nested groups are never inlined — they stay in residualGroup as full sub-trees and the executor evaluates them as usual.
When every leaf at the root is consumed and there are no nested groups, residualGroup is an empty AND-group (tautologically true). Callers may use hasResidualFilter as a hint to skip the per-row filter pass entirely.
When no leaf is consumed, callers should fall back to the existing apply(selectAll()) path unchanged.

Returns

BaseSetPlan<string>

Inherited from

AbstractQueryExecutor.planBaseSet

sort()

sort(rows, ctx?): Tag[]

Defined in: node_modules/@flyze/lib-db-models/gridify-filter/abstract.executor.d.ts:197

Stable, multi-key sort driven by expression.orderBy. Reuses the mapper to resolve values (multi-valued mappers compare by their first element). Null-handling: nulls last for ascending, nulls first for descending. Clauses whose mapper is missing/supported:false are silently skipped — callers should pre-check with canExecute() when the order matters for correctness.

Parameters

rows

readonly Tag[]

ctx?

void

Returns

Tag[]

Inherited from

AbstractQueryExecutor.sort
