# A single binary distribution of a JDK (e.g., OpenJDK 17 for Windows arm64) provides three
# different types of toolchains from the perspective of Bazel:

# The compilation toolchain, which provides the Java runtime used to execute the Java compiler, as
# well as various helper tools and settings.
#
# Toolchains of this type typically have constraints on the execution platform so that their Java
# runtime can run the compiler, but not on the target platform as Java compilation outputs are
# platform independent.
#
# Obtain the associated JavaToolchainInfo via:
#   ctx.toolchains["@bazel_tools//tools/jdk:toolchain_type"].java
toolchain_type(name = "toolchain_type")

# The Java runtime that executable Java compilation outputs (e.g., java_binary with
# create_executable = True) will run on.
#
# Toolchains of this type typically have constraints on the target platform so that the runtime's
# native 'java' binary can be run there, but not on the execution platform as building an executable
# Java target only requires copying or symlinking the runtime, which can be done on any platform.
#
# Obtain the associated JavaRuntimeInfo via:
#   ctx.toolchains["@bazel_tools//tools/jdk:runtime_toolchain_type"].java_runtime
toolchain_type(name = "runtime_toolchain_type")

# The Java runtime to extract the bootclasspath from that is then used to compile Java sources.
#
# As the bootclasspath is platform independent, toolchains of this type may have no constraints.
# Purely as an optimization to prevent unnecessary fetches of remote runtimes for other
# architectures, toolchains of this type may have constraints on the execution platform that match
# those on the corresponding compilation toolchain.
#
# Toolchains of this type are only consumed internally by the bootclasspath rule and should not be
# accessed from Starlark.
